UNITED STATES PATENT OFFICE LOOSE-LEAF HOLDER CASE Conrad J. Panfil,Sr., Milwaukee, Wis., assigner to The Heinn Company, Milwaukee, Wis., acorporation of Wisconsin Application June 21, 1947, Serial N0. 756,220

1 Claim. 1

This invention relates to a fitting for a brief case or the like toreceive and secure a loose-leaf book or other volume of papers withinthe case for easy use therewith.

An object of the invention is to provide a mounting within a brief caseto which a loose-leaf volume or other similar bound group of papers maybe removably secured.

Another object of the invention is to provide a unit comprising acarrying case and one or more loose-leaf volumes which may beselectively secured in or removed from the case and which may beconveniently used while in the case.

Another object is to provide means whereby eX- cessively large volumesmay be secured within a leather brief case without damage to the caseand which will permit the volume to be placed on one side while thebrief case is open.

Another object of the invention is to provide an inexpensive easilymanufactured base device which may be installed easily in most briefcases opening on three sides and which may be adapted to secure thereinany bound group of papers of appropriate size.

Another object is to provide such a base which may be easily andinstantly removed from the case when not required for use.

These and other objects and advantages of the invention will appear inthe following description of a preferred embodiment of the inventionillustrated in the accompanying drawings.

In the drawings:

Figure 1 is a top plan view of a brief case opened upon a table showingthe mounting base therein;

Fig. 2 is a vertical section of the base taken longitudinally thereofwith a loose-leaf volume secured therein;

Fig. 3 is a detail View showing the latch mechanism for the base;

Fig. 4 is a transverse section taken on line 4-4 of Fig. 2;

Fig. 5 is a perspective view of the brief case open and the mountingbase disassembled;

Fig. 6 is a view similar to Fig. 2 with the looseleaf volume partlyinserted and secured to the base;

Fig. 7 is an end view showing the brief case open as upon a table withthe loose-leaf volume secured to the base and lying in a closedposition; and

Fig. 8 is an end View showing the brief case open as upon a table withthe loose-leaf volume secured to the base and in an opened position foruse.

The brief case with which the invention is particularly adapted for useas shown in the drawings comprises in part a front and back cover I and2, a center section 3 connecting covers I and 2 along adjacent edges 4and a fabric border piece 5 extending around the free edges of eachcover. A slide fastener 6 along the edge of border 5 joins the bordersof the covers I and 2 when closed to completely enclose and protect thepapers carried within the case. A set of handles 'I may be provided forconvenience in carrying the case.

Any type of binder carrying a quantity of paper and having a substantialback member may be secured within the case.

The binder shown is of a loose-leaf type and includes a back member 8and two covers 9 to enclose the paper I0 therebetween. Back member 8should be slightly longer than the height of the paper so that ashoulder II is presented at each end of member 8 to be engaged by thecatch device to be described.

The base of the device for securing the binder in the case comprises asingle flat piece of metal I2 having a longitudinal flange I3 along oneside thereof. Base I2 is removably secured within the case by means of ahinge joint and hinge pin. One part I4 of the hinge joint is riveted tothe outer side of ilange I3 and the complementary part I5 of the hingejoint is riveted or otherwise secured to the inside of cover I of thebrief case so that the hinge axis of the joint is located near andparallel to the hinge joint between cover I and center section 3 of thebrief case and along the joint between the base I 2 and flange I3.

The width of base I2 may vary according to the size of binders to becarried within the case and is less than the width of center section 3.The length should be just slightly longer than the correspondingdimension of the binder.

The binder is secured within the brief case with the back member 8 ofthe binder disposed flat against base I 2.

A U-shaped channel-like metal bracket I6 is riveted or welded on oneside thereof along one end edge of base I2 and spaced from ange I3. Theopen side of bracket I6 faces inwardly on the top side of base I 2 topresent a slot to receive one end of the back 8 of the binder.

A second bracket I'I is similarly disposed at the opposite end of baseI2 and is pivotally secured thereto by a hinge joint.

One section I3 of the hinge joint is riveted to the end of base I2 withthe hinge axis transversely disposed thereof. The other section I 9 isriveted to the L-shaped bracket I1 which extends upward and over base I2to form with base I 2 a 3 slot to receive the opposite end of back 8 ofthe binder.

Bracket is biased in the position described by a spring bearing againstthe upright flange of an -shaped piece of metal 2l secured between hingesection i3 `and base I2.

A small metal handle 22 welded to the top of bracket i? and extendingaway from the bracket provides a handle for manipulating and opening thebracket I1 against the action of spring 29.

The binder is inserted within the case by placing one end of the backmember 8 in the slot formed by bracket I0, depressing handle 22 to openbracket I'I, placing the back 8 upon the base E2 and releasing handle 22so that brackets I6 and l1 engage the shoulders I I at the top andbottom, respectively, of the back member of the binder.

Almost any type of binder may be instantly removed or secured Within thecase. The binders may be of any thickness up to that `accommodated bythe brief case and are secured equally well so that the binder is alwaysdisposed against one side of the brief case. If the size of the binderpermits, additional papers may be carried in the case on the other sideof the brief case Without interference of the base device.

When the device is not in use it may be readily removed by withdrawingthe hinge pin 23 of the hinge joint securing base i2 to cover i. A smallextension 26 of one end of pin 23 bent 90 is provided for ease ininserting and withdrawing the pin.

Large binders carried within the case do not tend to break down thesides of the case. A reinorcing strip shown in dotted lines sewn withincover i opposite hinge section I5 and riveted together with the hingesection may be employed to further protect the leather cover againstdamage.

When the case is carried normally by the handles 'I the base i2 restsupon the center section 3 of the case and distributes the weight of thebinder throughout the case.

When the brief case is opened and laid fiat upon a 4table the bindersecured within the case may be also laid at upon the table with thetitle cover facing upward and the binder ready for use. 1n opening thebinder the back of the binder will readily lie flat upon the table as innormal use by virtue of the hinge joint between base I2 and the case.

The device is easily manufactured `and installed in any brief case ofthe type described.

Various embodiments of the invention may be employed within the scope ofthe accompanying claim.

I claim:

A loose leaf holder case comprising a pair of covers pivotally joined toopposite edges of a back member for the case of a width determining thenormal thickness of the case when closed, means secured to thecoextensive edges of said covers for closing the case, a binder forpaper having a fla-t back extending along the rear edges of papermounted therein, an L-shaped base member for supporting the back of saidbinder within said case having a base plate for attachment; to saidbinder `and an upstanding plate normal to said base plate for pivotalconnection with a cover of said case, an upstanding channel flangesecured yacross one end of said base plate and adapted to receive oneend of the back of said binder to secure the same against, displacementrelative t0 said base plate, a hinged flange secured across the otherend of said base plate and adapted t0 cooperate with said base plate toreceive the other end of the back of said binder therebetween, resilientmeans normally holding said hinged flange in operative position forsecuring said binder in place while providing for manual retraction ofthe hinged flange for release of the binder, and a hinge for connectingsaid base member and a cover of said case having separate complementarypivot plates secured to the upstanding plate of said base member and toa cover of said case and having a removable hinge pin joining the pivotplates, said binder being removable from said base plate upon retractionof said hinged flange and said base plate being removable from said casewith said binder upon removal of said hinge member', to clear the casefor other use.
